This is the same silly
" re-invent everything while designing new hardware" blunder
that torpedoed Ubuntu (and others?).

The Ubuntu team decided to reinvent the browser, email client,
media player and fundamentally rewrite everything
instead of simply port linux onto a handset.
That debacle sank in an excruciatingly slow demise.

Let us sincerely hope they just make a handset we can boot USB
and install whatever Debian/Gentoo/Arch system we want.

Beyond question whatever new and exciting UIX they design
will be greatly received by some and quietly disputed by many.

Better to also support the basic linux ecosystem
which already has globally 'baked in' support.

A more current example if is the very excellent GPD Pocket.
Crude, but it is an excellent success of hardware
hacked together which does support whatever Linux
you care to run on it.
The OS it ships with is 2nd best but who cares - the hardware works !
